CCNA: Cisco Certified Network Associate — Question 866

What is a characteristic of an SSID in wireless networks?

Answer options

• A. eliminates network piggybacking
• B. prompts a user for a login ID
• C. broadcasts a beacon signal to announce its presence by default
• D. must include a combination of letters and numbers

Correct answer: C

Explanation

The correct answer is C because SSIDs typically send out a beacon signal to notify devices of their presence. Option A is incorrect because while an SSID can help identify a network, it does not eliminate piggybacking. Option B is wrong as SSIDs do not prompt users for login information, and option D is also incorrect since SSIDs can consist of various characters, not just letters and numbers.
